Abstract

Multiple myeloma is an infectious disease characterized by the accumulation of abnormal plasma cells, a type of white blood cell, in the bone marrow. The main objective of this data analysis is to investigate the effect of Bun, Ca, Pcells and Protein risk factors on the survival time of multiple myeloma patients from diagnosis to death. In the survival data analysis, the observed random variable T is the time needed to achieve success. To explain a random variable, the cumulative distribution function or the probability density function can be used. In survival analysis, the function of the random variable that becomes important is the survival function and the hazard function which can be derived using the cumulative distribution function or the probability density function. In general, it is difficult to determine the survival function or hazard function of a population group with certainty. However, the survival function or hazard function can still be approximated by certain estimation methods. The Kaplan-Meier method can be used to find estimators of the survival function of a population. Meanwhile, to find the estimator of the cumuative hazard function, the Nelson-Aalen method can be used. From the variables studied, it turned out that the one that gave the most significant effect was the Bun variable, namely blood urea nitrogen levels using both the exponential and weibull distribution. However, by using the weibull distribution, the presence of Bence Jones Protein in urine also has a quite real effect

Abstract

This research aims to determine the effect of using interactive PowerPoint learning media on students' interest in learning mathematics. The population of this study was class VII students of Madrasah Tsanawiyah. Of the 3 existing classes, 2 classes were taken using the Random Sampling technique as samples, with one class as the experimental class and one class as the control class. This research uses the Quasi Experiment method with Nonequivalent Control Group Design. Treatment in the experimental class was given using interactive PowerPoint learning media, while in the control class learning was carried out conventionally using textbooks and LKS learning media. The results of the research show that there is an influence on interest in learning mathematics on students who use interactive PowerPoint learning media in experimental classes. This is proven by the results of observations of interest in learning of 81.60%. Inferential statistics using the t-test formula, obtained a tcount value of 13.30 which is greater than ttable with a value of 1.99 at a significance level of 5%. This shows that the null hypothesis is rejected and the alternative hypothesis is accepted

Abstract

The world was shocked by the emergence of COVID-19, which resulted in the paralysis of the world economy, especially in the Islamic banking sector, which resulted in financial performance. The purpose of this study is to analyze the factors that affect the financial performance of Islamic commercial banks through the Sharia Conformity and Profitability (SCnP) and CAMEL methods using 11 indicators, namely Sharia Investment Ratio, Sharia Income Ratio, Profit Sharing Ratio, Return on Assets, Return on Equity, Net Profit Margin, CAR, KAP, MAN, BOPO, and LDR. This study took two bank samples, namely Bank Syariah Indonesia and Bank Muamalat. The method used is a quantitative approach by looking at the annual financial statements of each bank. The results showed that the Sharia Conformity, Profitability, and CAMEL approach methods partially and simultaneously affected the financial performance of Islamic commercial banks during the covid-19 pandemic outbreak and post-pandemic.

Abstract

One part of mathematics that is widely felt to be beneficial in everyone's daily life is numeracy, especially the concept of numbers. Numbers are also in currency that needs to be understood early on by all parties. This qualitative study aims to describe how children who study in kindergarten get an introduction to Indonesian currency and explore more deeply about the process of stimulating numeracy skills, especially those running in PAUD BKB Kemas Nuri, Ciruas District, Serang Regency. the introduction of currency value in stimulating children's counting skills that is carried out is still complementary. This can be seen from the introduction activities, namely saving, playing the role of buying and selling or giving alms. In this position, the formation of certain characters is prioritized over children's counting skills. So an introduction with a clear focus can be planned for children.
